What did you have to do to get the Sierra Leone medal?
Avoid getting bitten by centipedes, scorpions, snakes and all other nasties in the makeshift showers, pray that you don't get the other type of malaria that was kicking about (the one that the tablets didn't protect against) then survive the rest of your time out their without needing to be casevac'd back with the particularly harsh local version of Deli Belly that some folk got.
Oh yeah, and avoid the poisonous snake that crawled out of my colleagues bergan at Lyneham.
